Abstract: 534,703. Covers, &c. for resisting fluid pressure. YORSTON. J., and TECALEMIT, Ltd. Sept. 15, 1939, No. 25898. [Class 123 (i)] [Also in Group I] A closure device, applicable generally in connection with covers or doors which are to be made fluid tight, is described as applied to a filter container. A recess 3a in the cover 1 is provided with inwardly projecting lugs 3b and the rim of the container 7 with beaded segments 7b which can pass between the lugs and, on slight rotation, support the container thereon. Sealing is effected by means of a ring 17 of resilient material which, under compression, engages the wall of the container and the inner wall of the recess 3a. The filter element which may be as described in Specification 501.667. [Group I], is supported between upper and lower plates 15, 18, the plate 18 being supported by a spring 19. The plate 15 has a central boss 15b screw-threaded internally for engagement with a tubular plug member 9 which passes through the cover. When the member 9 is turned by means of a tommy-bar 10, a wall 15c projecting upwardly from the rim of the plate 15 compresses the ring 17 and makes a fluid tight joint. The arrangement is such that the pressure on the sealing ring due to the pressure of fluid in the container is that of the fluid acting on the axially projected area of the ring 17.

Title: Improvements relating to electric protective systems
IPC: H02H3/40
Filed: 1948-10-05
Abstract: 665,465. Protective cut-out arrangements. BRATEN, T. L., and HOAL, H. Oct. 5, 1948. No. 25967/48. Class 38 (v). In an impednce relay arrangement two or more currents each being the vector sum or difference of components proportional to the current and voltage of a protected circuit, are rectified and co-operate in the operation of relay or other protective device. Fig. 2a shows one arrangement in which the current I in the protected circuit flows through an impedance zo, the voltage drop across the impedance being applied to a transformer IT. The voltage E of the protected circuit is applied to an auto transformer T. Bridge rectifiers L1, L2 are connected to tapping on the secondary winding of transformer IT and on the winding of transformer T, so that the current supplied to each rectifier is the vector sum or difference of components proportional to the current I and voltage E. The rectifiers supply windings Sp1, Sp2 on a relay R. The specification sets out with some mathematical proof, that if the relay R is arranged to operate when the combined effect of coils Sp1, Sp2 is zero, the relay operation depends solely on the impedance of the protected circuit and its phase angle. The specification also describes how, by suitably arranging the transformer taps, the operating characteric or impedance curve of the relay arrangement may be made a circle so disposed with respect to an origin that the arrangement functions as a distance relay or as a directional discriminative relay. Alternatively, the arrangement may function as a reactance relay. If it is desired that the impedance curve shall be an ellipse, three bridge rectifiers and associated circuits supply the relay R, Fig. 1a (not shown), or control the bias of a thyratron, Fig. 1b (not shown), or a transductor.

Title: Process for the manufacture of compounds with semi-cyclic double bond
IPC: C07C1/22
Filed: 1949-10-12
Abstract: Compounds with semi-cyclic double bond are manufactured by reducing an a  : b -unsaturated cycloalkenyl-carbonyl compound by the Wolff-Kishner method, e.g. by the action of hydrazine and alcoholates of mono- and bi-valent metals (especially of alkali metals, e.g. sodium ethoxide), in the presence or absence of solvents (preferably anhydrous, e.g. aliphatic alcohols such as ethanol or di- or tri-ethylene glycol, or dioxane), or by heating with an aqueous solution of hydrazine, an alkali hydroxide and a high-boiling solvent (e.g. di- or tri-ethylene glycol), or by forming nitrogen-containing derivatives (e.g. hydrazones, oximes or semi-carbazones) of the carbonyl compounds and further treating these correspondingly. Examples describe the reduction of: (1) and (10) D 2-2-formylcholestene to 2-methylenecholestane; and (2) and (4) D 1-cyclopentene aldehyde to methylenecyclopentane; (3) D 5:16-3b -acetoxypregnadiene-20-one to D 5 : 17-3b -acetoxypregnadiene (hydrolysed acetoxy groups being reacetylated with acetic anhydride and pyridine); (5) D 1 - cycloheptene aldehyde to methylenecycloheptane; (6) D 1-cyclopentadecene aldehyde to methylenecyclopentadecane; (7) b -cyclocitral to 2 : 2 : 6-trimethyl-1-methylenecyclohexane; (8) D 3-1 : 1-dimethyl-2-hydroxymethyl-3-formylcyclohexene to g -cyclogeraniol; (9) D 3-1 : 1-dimethyl-2-(31-hydroxy p  - 11 - butyl) - 3 - formylcyclohexene to g  - dihydroionol; (11) D 1 - tetrahydroacetophenone to ethylidenecyclohexane. Reference is also made in general to the reduction of D 16 - androstenyl - 17 - aldehydes and -ketones (which may be further substituted, e.g. by free, etherified or esterified hydroxy groups, especially in 3-, 11-, 12-, 14- or 21-position, and may contain additional double bonds, e.g. in 5 : 6-, 11 : 12- or 14 : 15-position), any further keto groups present being likewise reduced or temporarily protected by conversion to enol derivatives or acetals.  The products of this embodiment of the invention are useful intermediates for the preparation of 17-keto compounds of the androstane series by oxidative splitting of the semi-cyclic double bond.  A sample has been furnished under Sect. 2 (5) of D 5 : 17-3b -acetoxypregnadiene prepared by heating D 5 : 16 - 3b  - acetoxypregnadiene - 20 - one semicarbazone with a solution of sodium in ethanol in a sealed tube, reacetylating the hydrolysed acetoxy group with acetic anhydride and pyridine, and purifying the product by chromatography and crystallization.

Abstract: 730,666. Stop . motion. FAIRBAIRN LAWSON COMBE BARBOUR, Ltd. Oct. 15, 1953 [Oct. 22, 1952 ; Dec. 11, 1952], Nos. 26488/52 and 31364/52. Class 120(2). A stop motion for textile spinning, &c., machines, in which a detector element rests by virtue of its own weight against a yarn or thread is arranged so that movement of the detector upon thread breakage allows an eccentrically pivoted element to come into contact with and be driven by a rotating part of the machine such rotation causingmovement of a link resulting in predetermined stopping actions on the machine. In the embodiment shown a detector lever 63 is pivoted at 55. Also mounted on the pivot 55 is a link 47 to the other end of which, at pivot 49, is connected a rod or lever 43 which is acted upon, through a three armed lever 1, by a weight 3. An eccentric disc 51 is also mounted on the pivot 49. For normal operation the mechanism is in the position shown in Fig. 2 the eccentric being held up by a peg 53 engaging an extension 65 of the detector lever 63 and the weight acting through the rod 43 to hold the toggle mechanism as shown. On breakage of the thread 61 the detector 63 swings downwards, thus releasing the peg 53 from the extension 65 and permitting the eccentric disc to drop and contact the lower drawing roller 39 and be driven thereby. By this engagement the eccentric is moved in an upward direction causing the lever 43 to be similarly moved so that pivot 49 is moved through its dead centre position whereupon the lever 43 under the influence of weight 3 on the three armed lever 1 allows the latter to move. This causes the gripper rod 7 to be moved and the consequential gripping of the material passing through the conductor 75 by the gripper 9. At the same time, a stud 67 on the third arm of lever 1 engages the pressure lever 69 and relieves the pressure on the lower feeding roller, and, the support 31 for the rollers around which the apron 35 passes is moved about its pivot point to cause the apron to move away from its control roller 37.
